CoinDesk reported that the XRP Ledger (XRPL) is pushing for the introduction of a new automated market maker (AMM) system to strengthen its DeFi competitiveness. The draft disclosed by the XRP Ledger includes adding various models such as concentrated liquidity and stable swaps to the existing XRPL AMM functions. Additionally, a fully programmable smart AMM is planned to be developed as a separate specification in the future. The core of the proposal is to allow liquidity providers (LPs) to directly choose how the pool's prices are formed. The existing XRPL AMM has a structure that allocates liquidity uniformly across all price ranges, which is suitable for volatile assets but has been criticized for low capital efficiency for assets like stablecoins. The concentrated liquidity model can concentrate liquidity in specific price ranges where transactions mainly occur, allowing higher liquidity to be provided with the same capital. Stable swap is an optimized structure for trading assets with almost no price difference, such as dollar-pegged stablecoins or wrapped assets.
